In the bowl of a stand mixer fitted with a dough hook, stir together water, yeast and sugar. Allow to ferment for 5-10 minutes. Stir in 1 cup of flour, 2 tbsp olive oil, black pepper and salt. Knead on low adding remaining flour by the 1/4 cup, allowing each to be absorbed before adding more. Knead for about 7 minutes or until dough is smooth and pulls away from the side of the bowl. Place dough in a large oiled bowl and cover with plastic wrap or kitchen towel. Allow to rise in a warm draft free area until double in size, approximately 1 hour. Knead dough with your hands 2-3 times to deflate and divided into two rounds.
